Recycled Concrete Aggregate Tons per 100 Feet, 18 ft Road
Tons of recycled concrete aggregate per 100 feet of 18 foot road: about 29 tons at 4 inches deep. The strip is 18 ft × 100 ft = 1,800 square feet. On a job this long, half an inch of extra depth adds a lot of tons.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 22 | 2 |
| 4 in | 29 | 3 |
| 6 in | 43 | 4 |
| 8 in | 58 | 5 |
The math
- Area: 18 × 100 = 1,800 sq ft.
- Volume at 4 in: 1,800 × 0.333 = 600 cu ft (22 cubic yards).
- × 1.3 tons per yard = 29 tons.
What goes into the section
A 18-foot width allows two vehicles to pass carefully. Recycled concrete aggregate is crushed old concrete. It compacts well and often costs less than virgin stone, which makes it a common driveway and pad base. Crown the surface so water sheds to ditches on both sides.
Practical notes
- Phasing. Large tonnages are delivered over days; schedule spreading and compaction to keep up with trucks.
- Waste. Allow 5 to 10 percent.
- Hauling. Distance from the quarry or plant often costs as much as the material on long jobs; see asphalt hauling cost per ton.

Where recycled concrete aggregate fits
Good uses:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Less suited to:
- Near ponds, streams or sensitive plants, since fresh crush can raise pH
- Decorative top layers
- Drainage layers, unless the product is clean and screened
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 10x20 area at 4 inches takes about 3.2 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
